Dynamic DNS Update

In order to update DDNS (Dynamic DNS) on MikroTik router or RouterOS device, we have to make use of the scripting and scheduler feature.

There are some DDNS update scripts for popular providers contributed by the MikroTik community on MikroTik Wiki, which are listed as below.

• Dynamic DNS Update Script for ChangeIP.com
• Dynamic DNS Update Script for ChangeIP behind NAT
• Dynamic DNS Update Script for EveryDNS
• Dynamic DNS Update Script for dynDNS
• Dynamic DNS Update Script for dynDNS behind NAT
• Dynamic DNS Update Script for DNSoMatic.com
• Dynamic DNS Update Script for DNSoMatic.com behind NAT
• Dynamic DNS Update Script for Hurricane Electric DNS
• Dynamic DNS Update Script for No-IP DNS
